Temnothorax lichtensteini

Quick Summary

• Difficulty: Easy
• Origin & Habitat: Mediterranean region, from Iberian Peninsula to Western Turkey along the northern Mediterranean coastline, from 47°N in Austria to 37°N in Greece. Inhabits xerothermous open forests and warm, very sunny biotopes ^[2][3][1].
• Colony Type: Likely single-queen colonies (monogyne) based on typical Temnothorax patterns.
• Size & Growth:
  • Queen: 3-4 mm ^[1]
  • Worker: 2-3 mm ^[1]
  • Colony: Typically 20-50 workers, occasionally up to 200 ^[6][7]
  • Growth: Moderate
  • Development: Estimated 6-10 weeks based on typical Temnothorax development (Development time is temperature-dependent, warmer conditions within acceptable range accelerate development.)
• Antkeeping:
  • Temperature: Keep at room temperature around 20-24°C. These are Mediterranean ants that prefer warmth but can tolerate cooler indoor temperatures. A gentle heat gradient is beneficial but not essential.
  • Humidity: Moderate humidity. They naturally inhabit dry to moderately damp forest habitats. Keep nest substrate slightly moist but not waterlogged. Provide a water tube for drinking access.
  • Diapause: Yes, requires winter hibernation. Given their distribution reaching 47°N in Austria, they need a cold period of 2-3 months at 5-10°C during winter.
  • Nesting: Prefers tight, enclosed spaces. In captivity, they do well in small test tubes, Y-tong nests, or plaster nests with narrow chambers. They often nest under bark in nature, so provide dark, confined spaces ^[7][8].
• Behavior: Generally peaceful and non-aggressive. Workers are small (2-3 mm), timid, and forage alone, avoiding competition with larger ants ^[7]. They are arboreal and nest under bark, which allows them to coexist with invasive species like Lasius neglectus due to their cryptic habits ^[7]. They show fascinating corpse management behavior, burying fresh dead while transporting older corpses outside the nest ^[5]. Escape risk is moderate due to their small size, standard barriers work well.
• Common Issues: small colony size means they are sensitive to disturbance, handle gently., colonies may fail if kept too cold during winter, proper hibernation is essential., wild-caught colonies may carry parasites like Myrmicinosporidium durum that can affect survival ^[11]., slow colony growth can test beginner patience, don't overfeed or disturb founding colonies., tiny workers can escape through standard barriers, ensure tight-fitting lids and fine mesh., in Austria this species is protected as Endangered and it is illegal to collect wild queens. Check local laws before acquiring ^[12].

Housing and Nest Preferences

Temnothorax lichtensteini does well in small, enclosed nest setups. In the wild, they typically nest under bark or in dry branches within forests, so they prefer dark, tight spaces ^[7][8]. For captivity, a small test tube setup works well for founding colonies, while Y-tong (AAC) nests or small plaster nests with narrow chambers suit established colonies. These ants are arboreal by nature, so vertical space with climbing opportunities is appreciated. Avoid large, open spaces, they feel safer in compact chambers. A small outworld for foraging completes the setup.

Feeding and Diet

Like most Temnothorax, these ants are omnivorous but prefer small insects and sugar sources. Offer small live prey like fruit flies, pinhead crickets, or mealworm pieces. They readily accept sugar water, honey, or diluted syrup. Feed protein prey 2-3 times per week and keep a constant sugar source available. Given their small size, prey items should be appropriately sized, very small pieces that workers can manage. Remove uneaten prey after 24 hours to prevent mold. These guidelines are based on typical needs of small Temnothorax species.

Temperature and Seasonal Care

Keep these Mediterranean ants at room temperature, ideally 20-24°C. They tolerate a range of indoor temperatures but grow more actively in warmth. During summer, room temperature is usually sufficient. In winter, they require a hibernation period of 2-3 months at 5-10°C, this is essential for colony health and triggers reproductive swarming. Place the colony in a cool location (basement, garage, or refrigerator) during winter dormancy. Nuptial flights occur in July to August in the wild, so timing of hibernation affects reproductive development ^[9][1].

Behavior and Colony Dynamics

Temnothorax lichtensteini displays sophisticated social behaviors. Notably, they practice differentiated corpse management, fresh dead are buried within the nest using soil and nest material, while older corpses are transported outside ^[5]. This protects the colony from disease. Workers are small, timid foragers that move slowly and avoid confrontation ^[7]. They can coexist with invasive ants like Lasius neglectus due to their cryptic habits and small colony size. Colonies remain relatively small (typically under 200 workers), so they won't overwhelm your ant setup. The East Mediterranean population serves as host for the slave-making ant Temnothorax gordiagini, but this is not a concern for captive colonies in most regions ^[3]. Queens have been recorded living up to 17 years under optimal conditions ^[10].

Health and Common Problems

Watch for signs of stress in these small ants. Wild-caught colonies may carry the fungal parasite Myrmicinosporidium durum, which is visible as spores through the ant's body wall and can affect longevity ^[11]. Infected workers appear normal but often die after hibernation. Colonies are sensitive to disturbance during founding, minimize vibrations and avoid checking on them too frequently. Their small size means escape prevention is important, standard barrier gel or fluon on container edges works well. Overfeeding leads to mold problems, so keep portions small and remove uneaten food. Also note that in Austria this species is protected (Endangered), so if you live there, do not collect from the wild ^[12].
